Kind Code:
A1
Abstract:
Disclosed is a quickly-disassembled and assembled sound insulation enclosure structure for closed construction of a subway station. The structure comprises a fireproof sound insulation enclosure, a movable door structure and a quickly-disassembled structure, wherein the fireproof sound insulation enclosure is a closed structure installed in the subway station, and is used for enclosing a wall to be disassembled in the subway station; and the movable door structure is arranged on the fireproof sound insulation enclosure, and the fireproof sound insulation enclosure is fixed to the wall to be disassembled by means of the quickly-disassembled structure.
